There are two options:
1) I would be the Daycare centre person and charge you exorbant prices for letting your pokemon stay in my ranch, procreate and go up levels. And I would make sure that your pokemon wouldn't evolve when it reaches the right level and I wouldn't even call you unless it was to pick up an egg. 'cause I'm evil like that.
2) I would be (in the case of Kanto, Jhoto and Sinnoh games) your non-existent father.
But honestly, I would go on my own random adventure, going wherever I want, whenever.
